Ben wants to model how the motion of particles changes with temperature. he considers water in an iron pot. ben draws a model to show how the water particles and iron particles move at room temperature. then, he draws a second model to show how the water particles and iron particles move as the pot of water is heated. how should ben’s second model differ from the first?

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?
